Definitions

  • the present invention is directed to an auxiliary damper for use with rubber or other spring suspension mountings. More particularly, the present invention is directed to an auxiliary surface-effect damper that can be confined within the existing space envelope occupied by the primary suspension mounting.
  • Laminated rubber and metal mounts have been around for some time.
  • focalization of elastomeric mounts has been employed to decouple the translational and rotational vibrational modes in order to greatly simplify the required mounting system needed to provide the necessary damping and isolation.
  • the present invention proposes to add auxiliary damping to a system to reduce movement at or near the system's resonance frequency.
  • the system may employ an elastomeric spring mount or other type of spring mount in the primary suspension, and preferably will include focalization.
  • An elastomeric sleeve bonded to a rigid collar that surrounds a support bolt for a pair of primary mounts provides a workable surface element for surface-effect (frictional and hysteretic, combined) damping.
  • the bolt secures the primary suspension mountings and auxiliary damper to a first one of a supported element and a support.
  • a metallic sleeve which has a C-shaped cross section and an internal peripheral surface which has cylindrical protrusions formed thereon surrounds the elastomeric sleeve and the protrusions work the elastomer to dissipate energy by hysteresis.
  • the upper flange of the C-shaped sleeve overlies and the lower flange underlies the other of the supported element and the support.
  • the distance between the flanges exceeds the maximum thickness of that other member and the outer diameter of the central portion of the C-shaped member is smaller than the diameter of the opening in the support.
  • This clearance between the sleeve and its received member permit vibrations of low amplitude, high frequency to be isolated (i.e., not transmitted) from the support vis-a-vis the supported element.
  • the vibration of the support exceeds this minimally permitted magnitude as, for example, when the disturbance frequency approaches the natural, or resonant, frequency of the system, the auxiliary damper will dissipate the objectionable motion-inducing energy and restore controlled movement between the supported element and the support.
  • FIG. 1 is isometric schematic depiction of the application of the auxiliary damper of the present invention in a cab mounting system
  • FIG. 2 is a cross-sectional side view of the auxiliary damper of the present invention shown installed within the primary suspension system;
  • FIG. 3A is an end view of the cylindrical spool of the auxiliary damper of the present invention.
  • FIG. 3B is a cross-sectional side view of the cylindrical spool as seen along line 3B--3B in FIG. 3A;
  • FIG. 4 is a cross-sectional side view of an alternative application of the auxiliary damper of the present invention.
  • FIG. 5 is a side view of the auxiliary damper of the present invention in the application of FIG. 1.
  • the auxiliary damper 12 of the present invention is shown in FIG. 1 as a part of a mounting system 20 which includes a primary suspension member 11.
  • a primary suspension member 11 As depicted in FIG. 1, four focalized primary suspension members 11 are used to support a cab 13 relative to a support or frame 25 (FIG. 2).
  • a minimum of three members 11 are required to achieve focalization, which results in decoupling of the rotational and translational modes of vibration.
  • Focalization is well known in the industry and has been aptly described in commonly assigned U.S. Pat. No. 2,685,425, which is hereby incorporated by reference.
  • auxiliary damper 12 of the present invention is received within a pair of aligned primary suspension members 11 which are held in alignment by suspension bolt 17.
  • Bolt 17 secures inner sleeve 14 to supported element 19 which is, in this utilization, a floor portion of cab 13.
  • Cab 13 may, for example, be the passenger compartment of a tractor, combine, or other farm or industrial equipment.
  • Primary suspension members 11 are preferably elastomeric mounts of laminated metal-and-elastomer construction having upper (21) and lower (23) plates laminated to the respective upper most and lowermost elastomeric surface layers.
  • Lower plates 23 are positioned on either side of a support 25 which, in this application, may comprise a portion of the vehicular frame. Lower plates 23 are clamped against a pair of split-ring members 29 which facilitate assembly of the suspension system 20 with support 25.
  • Support 25 has an opening formed therein with an innermost periphery 31 having a diameter D 1 .
  • Split-ring members 29 each have a flange 33 which has a height of one-half the thickness of support 25 and a width extending from a maximum diameter which is generally equal to D 1 and a minimum diameter D 2 .
  • An elastomeric sleeve 16 having an outer diameter D 3 is bonded to an external peripheral portion of inner sleeve 14 which is preferably of a metallic or plastic material.
  • Metallic spacer washers 27 are employed to preload the elastomer of primary suspension members 11 by an amount permitted by the combined length of washers 27 and sleeve 14.
  • a cylindrical spool 18 (see FIGS. 3A-B) has an inner diameter D 4 which is less than the outer diameter D 3 of elastomeric sleeve 16 to create an interference fit between the two.
  • Upper flange 22 overlies split-rings 33 and lower flange 24 underlies said rings.
  • the spacing between flanges 22 and 24 exceeds the combined thickness of rings 33 and, in its centered, at rest position, spool 18 will not engage rings 33.
  • the inner periphery of spool 18 has a plurality of protrusions 26 thereon which provide hysteresis damping when spool 18 is moved relative to elastomeric sleeve 16.
  • Minimum outer diameter D 5 of spool 18 is less than the maximum diameter D 2 of flanges 33 on split-rings 29.
  • Lower suspension member 11 is positioned and nut 35 tightened to bring each of upper plates 21 into engagement with its respective spacer washer 27 to provide the designed preload of the elastomer in members 11.
  • the weight of cab 13 can be taken into account to equalize the loading on upper and lower members 11 by varying the unloaded thickness of the mounts and/or their respective static spring rates.
  • the paired primary suspension members 11 will isolate the cab 13 from low amplitude, generally high frequency, vibrations through the "spring action" of the elastomeric layers, the lower of the paired members 11 preventing rebound motion.
  • the flanges 33 of split-rings 29 will engage the overlying (22) and underlying (24) flanges successively causing spool 18 to translate relative to elastomeric sleeve 16.
  • This translational motion will induce surface-effect damping (i.e., damping having both frictional and hysteresis components), causing this high amplitude vibrational energy to be dissipated as heat.
  • the auxiliary damper 12 maintains a smooth ride through any transition through the resonant frequency occurring during low speed operation of the vehicle.
  • the smaller diameter D 5 vis-a-vis the inner diameter D 2 of rings 29 permits some relative lateral and torsional movement of support 25 relative to cabin 13 without engaging the damper 12.
  • the auxiliary damper 12 provides a necessary and beneficial function of damping out excess motion, its engagement will result in some cab movement and, therefore, some transmission of vibration to the passenger compartment; hence, the preference for the isolation of spool 18 from engagement with support 25 when damping is not needed.
  • each of the suspension members 11 and associated auxiliary dampers 12 are canted from vertical some 21.5° to provide the desired focalization of the system 20. This will provide a center of restraining elastic force which coincides with the center of gravity of cab 13.
  • FIG. 4 A second embodiment of the present invention is depicted in FIG. 4 generally at 12a. While for most applications the spring member of the primary suspension member will most preferably be an elastomeric mount of laminated construction, for some applications it may be desirable to utilize a coil spring 11a. The principles of operation of the auxiliary damper 12a remains unchanged in this embodiment. The restorative and damping forces of the primary suspension are simply provided by a pair of coil springs 11a depicted in FIG. 4 as conically coiled.
  • the present invention of an auxiliary surface-effect damper which is entirely contained within the existing suspension mount provides an easy, inexpensive solution to what is potentially a complex problem of what to do about damping large amplitude vibration associated with the resonant frequency of the primary suspension mount.
